Samsung’s DeX is one of the most useful additions to the Samsung ecosystem since the S Pen. The platform allows users to multitask seamlessly with their Windows or Mac systems in tandem with their Samsung device. It was first introduced with the Galaxy S8 and continues to be a cornerstone feature in any Samsung device.

That said, the feature – which turns a Samsung smartphone or tablet into a portable computer – seems to be making its first cut to keep up with the times. Samsung’s DeX will be halting support for Windows 7 come January 2022. This comes as no surprise as Microsoft themselves has marked Windows 7, 8 and 8.1 for support termination in the near future. If you’re on Windows 10 or later, you won’t have to worry about this change.

In addition to ending support for Windows 7, it looks like MacOS users who have a Samsung device will also be out of luck as Mac OS support will also be dropped come January 2022. Users have been getting a pop up notice from the app stating that support is ending for the app and it will not be available for download starting January 2022. No clarification or explanation has been given for the ending of support for MacOS.

If you haven’t used Samsung DeX, it’s one of the first iterations of screen/device mirroring that made its way to Android. The feature allows users to connect their smartphones and/or tablets to a screen via HDMI or to a PC through WiFi. Once connected users will be able to access a desktop version of OneUI with support drag and drop file transfers.
